TL;DR: just pretend some code repo exists, interact with it, and GPT will happily fill in the blanks.

Example:

    # Start with the "act as a terminal" preface (https://github.com/f/awesome-chatgpt-prompts#act-as-a-linux-terminal)

    git clone https://github.com/shesek/veterinarian-app
    cd veterinarian-app

    node src/webserver.js --port 5051

    curl -X POST localhost:5051/api/customers/create -d name='Bob Marlin' -d phone=050-1112223 -d email=bobml@gmail.com

    curl localhost:5051/api/customers?fields=id,uri,name,phone,email,created_at,updated_at,num_animals,next_visit

    # src/webserver.js will now exists with an implementation of the API endpoints.

    ./util/db-dump-json.sh --include customers,animals --out-file dump.json

    # db-dump-json.sh will now exists, including argument parsing/validation and usage help text.

The twitter thread lists some more examples. It's pretty mind blowing to me that this is possible!
